In a few weeks we are shooting all green screen for a digital set. Is there tips for making this easier?For example we have created 4x8x2.5' platform that will be used for our cryochambers. On our test shoot I filmed these from a locked off position but could not align the digital cubes( modeled at 4x8x2.5) with the ground plane. Other then measurements and marks is this a way to shoot locked off and have an easy time compositing the digital set?
